Definitions
- the present invention relates to refuse collection vehicles and, more particularly, to rear hopper refuse collection vehicles.
- Rear hopper refuse collection trucks are designed to handle large, wheeled refuse containers, typically having capacities of 2, 3, 4, 6, 8 and 10 cubic yards. These refuse containers are formed with a trunnion along one side of their open upper ends, and are secured to the rear of the truck adjacent the loading sill of the hopper. They are pivoted about their trunnions by, e.g., a push bar (for containers of up to 4 cubic yard capacity) and a winch having a cable and hook or a hydraulic cylinder (known as a reeving cylinder) (for containers of 5 cubic yard capacity or more) in order to tip the containers and discharge their contents into the hopper.
- a push bar for containers of up to 4 cubic yard capacity
- a winch having a cable and hook or a hydraulic cylinder (known as a reeving cylinder) (for containers of 5 cubic yard capacity or more) in order to tip the containers and discharge their contents into the hopper.
- the container must be pivoted about the trunnion a sufficient amount so that the refuse contained therein will slide out, but not so far that the center of gravity of the container passes over the pivot axis defined by the trunnion, in which case the container would continue to rotate about the trunnion and either fall into the hopper or hit and damage the top edge of the hopper opening.
- the hoppers of some refuse collection trucks have been provided with a stop in a form of a beam that spans the hopper opening near the top of the opening.
- the beam is rigidly affixed to the side walls of the hopper and serves as a guard to prevent an “over-tipped” container from hitting and damaging the hopper opening.
- Such a fixed stop bar works well with standard-size containers, but may not be effective for other sizes or shapes for containers. Also, while the fixed stop bar protects the hopper opening from damage due to “overtipped” containers, the stop bar instead can become damaged.
- a stop bar for use in a refuse collection vehicle with a rear hopper having an opening defined by sidewalls, an upper edge, and a loading sill.
- the stop bar includes an elongated bar with support arms secured to each of its ends.
- the support arms are pivotally mounted to the sidewalls of the hopper.
- Two stops are provided for limiting the pivoting movement of the stop bar between a first, non-engaged position and a second, fully engaged position. These stops engage at least one, and preferably both of the support arms.
- each support arm is pivotally mounted to a bracket secured to the hopper sidewall.
- Both the bracket and the support arm include a flange, with each flange supporting one of the stops.
- the stop bar may advantageously include a spring to cushion the impact of a refuse container as the stop bar moves from its first position to the second position, and also to bias the stop bar toward its first position.
- FIG. 1 is a perspective view of a rear hopper refuse collection truck and a refuse container.
- FIG. 2 is a fragmentary plan view of a stop bar pursuant to the present invention taken along line 2 — 2 of FIG. 1 .
- FIG. 3 is a side view, impartial cross section, taken along line 3 — 3 of FIG. 2 showing the stop bar in its initial position when first engaged by a container.
- FIG. 4 is a side view similar to FIG. 3 showing the stop bar pivoted to its second position.
- FIG. 1 a perspective view of a rear hopper refuse collection truck, generally indicated by 10 , with which a stop bar according to the present invention may be advantageously used.
- the truck 10 includes a hopper portion 12 depending from the truck generally rearward of the rear wheels 14 into which refuse is dumped for compaction.
- the hopper 12 includes a rearward-facing opening generally defined by the sidewalls 16 of the hopper 12 , a lower loading edge or sill 18 , and an upper edge 20 .
- a rollable refuse container 22 having an open upper end including, on one side, a trunnion bar 24 that extends beyond the edges of the container 22 .
- the container 22 is positioned with the trunnion bar 24 adjacent the loading edge 18 of the hopper 12 .
- the trunnion bar 24 is then secured to the truck 10 by various well-known means, such as pivotable locking latches 26 .
- the container 22 is then pivoted about the trunnion 24 by means of, e.g., an hydraulically actuated push bar 28 , a drum winch 30 having a cable and hook (not shown), or a hydraulic cylinder 31 .
- the hopper 12 is provided with a stop bar, generally designated 32 , that spans the opening in the hopper 12 adjacent the upper edge 20 .
- the stop bar 32 is located so that it permits the container 22 to tip a sufficient amount to allow its contents to be discharged without the stop bar 32 interfering with the movement of the refuse into the hopper 12 .
- the stop bar 32 is made of an elongated section of square steel tubing 34 that has a support arm 36 secured to each end by, e.g., welding.
- Each support arm 36 includes a pivot mount 37 that secures the support arm 36 to a mounting bracket 38 secured to the sidewalls 16 of the hopper by, e.g., bolts 39 .
- the stop bar 32 is provided means that limit the pivotal motion of the stop bar 32 when engaged by a tipped container between a first, non-engaged position (FIG. 3) to a second, engaged position (FIG. 4 ).
- the stop bar 32 is provided with a pair of motion-limiting stops.
- at least one (and preferably both) of the support arms 36 have stops 40 and 42 associated therewith.
- the stops 40 , 42 limit the pivotal motion of the support arms by limiting the extent of rotation of the support arms 36 with respect to their mounting brackets 38 .
- both the support arm 36 and its associated mounting bracketing 38 are formed with a generally perpendicularly-oriented flange 44 and 46 , respectively.
- Each one of the flanges 44 , 46 support one of the stop members 40 , 42 , with the other of the flanges engaging one of the stops at the first and second positions of the stop bar 32 .
- stop 40 comprises a length of triangular bar stock welded to the flange 46 so that the hypotenuse forms an abutment surface that engages the flange 44 on the support arm 36 when the stop bar 32 is pivoted to its second position (FIG. 4 ).
- Stop 42 is secured to the flange 44 on the support arm 36 and comprises a threaded bolt 48 received in a through-hole in the flange 44 .
- the head of the bolt 48 abuts the flange 46 on the mounting bracket 38 when the support arm is in the first position (FIG. 3 ).
- the bolt 48 may be secured to the flange by a pair of nuts 50 , one nut 50 being on the shaft of the bolt 48 on either side of the flange 44 . As can be appreciated, this configuration allows for the nuts 50 to be moved along the threaded shaft of the bolt 48 to provide for some limited adjustment of the first position of the stop bar 32 .
- the stop bar 32 may be mounted to the truck 10 so that gravity urges the stop bar 32 to the position of FIG. 3 .
- the stop bar assembly 32 may include at least one spring 52 to bias the stop arm 32 towards its first position.
- the spring 52 also opposes the movement of the stop bar towards its second position, thus providing some cushioning when the stop bar 32 is engaged by a tipped container 22 .
- one end of the spring 52 is secured to a bracket 54 affixed to the support arm 36 , and the other end is secured to a bracket 56 affixed to the hopper sidewalls 16 .
- the stop bar 32 maybe provided with one or more projecting ears 58 secured to the stop bar 32 intermediate the two ends of the tube member 34 .
- These ears 58 which may be secured to the tube 34 by welding, provide additional support surfaces for engagement with containers of various sizes and configurations.
